TECHNICAL FIELD

This relates generally to electronic devices with touch-sensitivesurfaces, including but not limited to electronic devices withtouch-sensitive surfaces that display electronic documents.

BACKGROUND

The use of touch-sensitive surfaces as input devices for computers andother electronic computing devices has increased significantly in recentyears. Exemplary touch-sensitive surfaces include touch pads and touchscreen displays. Such surfaces are widely used to manipulate electronicdocuments on a display.

Exemplary manipulations include navigating and editing an electronicdocument. A user may need to perform such manipulations in anyapplication that includes electronic document viewing and editingcapabilities (e.g., a drawing application, a presentation application(e.g., Keynote from Apple Inc. of Cupertino, Calif.), a word processingapplication (e.g., Pages from Apple Inc. of Cupertino, Calif.), awebsite creation application (e.g., iWeb from Apple Inc. of Cupertino,Calif.), or a spreadsheet application (e.g., Numbers from Apple Inc. ofCupertino, Calif.)).

But existing methods for navigating and editing documents are cumbersomeand inefficient, especially on devices with a small form factor, such ashandheld or pocket-sized devices. In addition, existing methods takelonger than necessary, thereby wasting energy. This latter considerationis particularly important in battery-operated devices.

SUMMARY

Accordingly, there is a need for electronic devices with faster, moreefficient methods and interfaces for navigating and editing anelectronic document. Such methods and interfaces may complement orreplace conventional methods for navigating and editing an electronicdocument. Such methods and interfaces reduce the cognitive burden on auser and produce a more efficient human-machine interface. Forbattery-operated devices, such methods and interfaces conserve power andincrease the time between battery charges.

DESCRIPTION OF EMBODIMENTS

Described below are devices and methods that allow a user to efficientlynavigate and edit electronic documents. The methods are particularlyuseful on portable devices with small displays, including handheld orpocket-sized devices (e.g., smart phones). For such portable devices, auser may find himself (or herself) constantly needing to manuallyreadjust the text display size as the user moves through the document,from a very small text display size to get an overview of the documentto a larger text display size to clearly see the text being edited.These adjustments require multiple inputs and extensive hand-eyecoordination. Such adjustments quickly become annoying and tiresome tousers. The methods described herein include:

-   -   Automatically zooming in on a user-specified insertion point        when entering a document editing mode and displaying the text at        the insertion point at a target text display size for easy        viewing and editing;    -   Easily modifying the target text display size from a default        value to a user-adjusted value;    -   Automatically adjusting the display magnification to maintain a        target text display size as the insertion point is moved between        areas in a document with different font sizes;    -   Automatically zooming out at the completion of a text selection        gesture to see the entire portion of text that has been        selected;    -   Automatically zooming to display an object at a size that        accommodates the object or, when the object contains editable        text, automatically zooming to display the editable text within        the object at a size that accommodates the text; and    -   Automatically switching back and forth from a user-specified        magnification level in a document-display mode to a predefined        document-editing magnification level in an editing mode.

These methods greatly reduce the number of steps that a user has toperform to navigate and edit a document, thereby increasing efficiencyand ease of use when performing these tasks.

Below, FIGS. 1A-1 B, 2, 3, and 12-17 provide a description of exemplarydevices. FIGS. 4A-4B and 5A-5AA illustrate exemplary user interfaces fornavigating and editing an electronic document. FIGS. 6A-6E, 7A-7B,8A-8B, 9A-9B, 10, 11A-11 b are flow diagrams illustrating methods ofnavigating and editing an electronic document. The user interfaces inFIGS. 5A-5AA are used to illustrate the processes in FIGS. 6A-6E, 7A-7B,8A-8B, 9A-9B, 10, 11A-11B.

Determiningmovement of the point of contact, which is represented by a series ofcontact data, may include determining speed (magnitude), velocity(magnitude and direction), and/or an acceleration (a change in magnitudeand/or direction) of the point of contact. These operations may beapplied to single contacts (e.g., one finger contacts) or to multiplesimultaneous contacts (e.g., “multitouch”/multiple finger contacts). Insome embodiments, contact/motion module 130 and display controller 156detect contact on a touchpad.

Contact/motion module 130 may detect a gesture input by a user.Different gestures on the touch-sensitive surface have different contactpatterns. Thus, a gesture may be detected by detecting a particularcontact pattern. For example, detecting a finger tap gesture includesdetecting a finger-down event followed by detecting a finger-up (liftoff) event at the same position (or substantially the same position) asthe finger-down event (e.g., at the position of an icon). As anotherexample, detecting a finger swipe gesture on the touch-sensitive surfaceincludes detecting a finger-down event followed by detecting one or morefinger-dragging events, and subsequently followed by detecting afinger-up (lift off) event.

FIG. 1B is a block diagram illustrating exemplary components for eventhandling in accordance with some embodiments. In some embodiments,memory 102 (in FIGS. 1A and 1B) or 370 (FIG. 3) includes event sorter170 (e.g., in operating system 126) and a respective application 136-1(e.g., any of the aforementioned applications 137-151, 155, 380-390).

Event sorter 170 receives event information and determines theapplication 136-1 and application view 191 of application 136-1 to whichto deliver the event information. Event sorter 170 includes eventmonitor 171 and event dispatcher module 174. In some embodiments,application 136-1 includes application internal state 192, whichindicates the current application view(s) displayed on touch sensitivedisplay 112 when the application is active or executing. In someembodiments, device/global internal state 157 is used by event sorter170 to determine which application(s) is (are) currently active, andapplication internal state 192 is used by event sorter 170 to determineapplication views 191 to which to deliver event information.

In some embodiments, application internal state 192 includes additionalinformation, such as one or more of: resume information to be used whenapplication 136-1 resumes execution, user interface state informationthat indicates information being displayed or that is ready for displayby application 136-1, a state queue for enabling the user to go back toa prior state or view of application 136-1, and a redo/undo queue ofprevious actions taken by the user.

Event monitor 171 receives event information from peripherals interface118. Event information includes information about a sub-event (e.g., auser touch on touch-sensitive display 112, as part of a multi-touchgesture). Peripherals interface 118 transmits information it receivesfrom I/O subsystem 106 or a sensor, such as proximity sensor 166,accelerometer(s) 168, and/or microphone 113 (through audio circuitry110). Information that peripherals interface 118 receives from I/Osubsystem 106 includes information from touch-sensitive display 112 or atouch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripheralsinterface 118 at predetermined intervals. In response, peripheralsinterface 118 transmits event information. In other embodiments,peripheral interface 118 transmits event information only when there isa significant event (e.g., receiving an input above a predeterminednoise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit viewdetermination module 172 and/or an active event recognizer determinationmodule 173.

Hit view determination module 172 provides software procedures fordetermining where a sub-event has taken place within one or more views,when touch sensitive display 112 displays more than one view. Views aremade up of controls and other elements that a user can see on thedisplay.

Another aspect of the user interface associated with an application is aset of views, sometimes herein called application views or userinterface windows, in which information is displayed and touch-basedgestures occur. The application views (of a respective application) inwhich a touch is detected may correspond to programmatic levels within aprogrammatic or view hierarchy of the application. For example, thelowest level view in which a touch is detected may be called the hitview, and the set of events that are recognized as proper inputs may bedetermined based, at least in part, on the hit view of the initial touchthat begins a touch-based gesture.

Hit view determination module 172 receives information related tosub-events of a touch-based gesture. When an application has multipleviews organized in a hierarchy, hit view determination module 172identifies a hit view as the lowest view in the hierarchy which shouldhandle the sub-event. In most circumstances, the hit view is the lowestlevel view in which an initiating sub-event occurs (i.e., the firstsub-event in the sequence of sub-events that form an event or potentialevent). Once the hit view is identified by the hit view determinationmodule, the hit view typically receives all sub-events related to thesame touch or input source for which it was identified as the hit view.

Active event recognizer determination module 173 determines which viewor views within a view hierarchy should receive a particular sequence ofsub-events. In some embodiments, active event recognizer determinationmodule 173 determines that only the hit view should receive a particularsequence of sub-events. In other embodiments, active event recognizerdetermination module 173 determines that all views that include thephysical location of a sub-event are actively involved views, andtherefore determines that all actively involved views should receive aparticular sequence of sub-events. In other embodiments, even if touchsub-events were entirely confined to the area associated with oneparticular view, views higher in the hierarchy would still remain asactively involved views.

Event dispatcher module 174 dispatches the event information to an eventrecognizer (e.g., event recognizer 180). In embodiments including activeevent recognizer determination module 173, event dispatcher module 174delivers the event information to an event recognizer determined byactive event recognizer determination module 173. In some embodiments,event dispatcher module 174 stores in an event queue the eventinformation, which is retrieved by a respective event receiver module182.

In some embodiments, operating system 126 includes event sorter 170.Alternatively, application 136-1 includes event sorter 170. In yet otherembodiments, event sorter 170 is a stand-alone module, or a part ofanother module stored in memory 102, such as contact/motion module 130.

In some embodiments, application 136-1 includes a plurality of eventhandlers 190 and one or more application views 191, each of whichincludes instructions for handling touch events that occur within arespective view of the application's user interface. Each applicationview 191 of the application 136-1 includes one or more event recognizers180. Typically, a respective application view 191 includes a pluralityof event recognizers 180. In other embodiments, one or more of eventrecognizers 180 are part of a separate module, such as a user interfacekit (not shown) or a higher level object from which application 136-1inherits methods and other properties. In some embodiments, a respectiveevent handler 190 includes one or more of: data updater 176, objectupdater 177, GUI updater 178, and/or event data 179 received from eventsorter 170. Event handler 190 may utilize or call data updater 176,object updater 177 or GUI updater 178 to update the application internalstate 192. Alternatively, one or more of the application views 191includes one or more respective event handlers 190. Also, in someembodiments, one or more of data updater 176, object updater 177, andGUI updater 178 are included in a respective application view 191.

A respective event recognizer 180 receives event information (e.g.,event data 179) from event sorter 170, and identifies an event from theevent information. Event recognizer 180 includes event receiver 182 andevent comparator 184. In some embodiments, event recognizer 180 alsoincludes at least a subset of: metadata 183, and event deliveryinstructions 188 (which may include sub-event delivery instructions).

Event receiver 182 receives event information from event sorter 170. Theevent information includes information about a sub-event, for example, atouch or a touch movement. Depending on the sub-event, the eventinformation also includes additional information, such as location ofthe sub-event. When the sub-event concerns motion of a touch the eventinformation may also include speed and direction of the sub-event. Insome embodiments, events include rotation of the device from oneorientation to another (e.g., from a portrait orientation to a landscapeorientation, or vice versa), and the event information includescorresponding information about the current orientation (also calleddevice attitude) of the device.

Event comparator 184 compares the event information to predefined eventor sub-event definitions and, based on the comparison, determines anevent or sub-event, or determines or updates the state of an event orsub-event. In some embodiments, event comparator 184 includes eventdefinitions 186. Event definitions 186 contain definitions of events(e.g., predefined sequences of sub-events), for example, event 1(187-1), event 2 (187-2), and others. In some embodiments, sub-events inan event 187 include, for example, touch begin, touch end, touchmovement, touch cancellation, and multiple touching. In one example, thedefinition for event 1 (187-1) is a double tap on a displayed object.The double tap, for example, comprises a first touch (touch begin) onthe displayed object for a predetermined phase, a first lift-off (touchend) for a predetermined phase, a second touch (touch begin) on thedisplayed object for a predetermined phase, and a second lift-off (touchend) for a predetermined phase. In another example, the definition forevent 2 (187-2) is a dragging on a displayed object. The dragging, forexample, comprises a touch (or contact) on the displayed object for apredetermined phase, a movement of the touch across touch-sensitivedisplay 112, and lift-off of the touch (touch end). In some embodiments,the event also includes information for one or more associated eventhandlers 190.

In some embodiments, event definition 187 includes a definition of anevent for a respective user-interface object. In some embodiments, eventcomparator 184 performs a hit test to determine which user-interfaceobject is associated with a sub-event. For example, in an applicationview in which three user-interface objects are displayed ontouch-sensitive display 112, when a touch is detected on touch-sensitivedisplay 112, event comparator 184 performs a hit test to determine whichof the three user-interface objects is associated with the touch(sub-event). If each displayed object is associated with a respectiveevent handler 190, the event comparator uses the result of the hit testto determine which event handler 190 should be activated. For example,event comparator 184 selects an event handler associated with thesub-event and the object triggering the hit test.

In some embodiments, the definition for a respective event 187 alsoincludes delayed actions that delay delivery of the event informationuntil after it has been determined whether the sequence of sub-eventsdoes or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series ofsub-events do not match any of the events in event definitions 186, therespective event recognizer 180 enters an event impossible, eventfailed, or event ended state, after which it disregards subsequentsub-events of the touch-based gesture. In this situation, other eventrecognizers, if any, that remain active for the hit view continue totrack and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata183 with configurable properties, flags, and/or lists that indicate howthe event delivery system should perform sub-event delivery to activelyinvolved event recognizers. In some embodiments, metadata 183 includesconfigurable properties, flags, and/or lists that indicate how eventrecognizers may interact with one another. In some embodiments, metadata183 includes configurable properties, flags, and/or lists that indicatewhether sub-events are delivered to varying levels in the view orprogrammatic hierarchy.

In some embodiments, a respective event recognizer 180 activates eventhandler 190 associated with an event when one or more particularsub-events of an event are recognized. In some embodiments, a respectiveevent recognizer 180 delivers event information associated with theevent to event handler 190. Activating an event handler 190 is distinctfrom sending (and deferred sending) sub-events to a respective hit view.In some embodiments, event recognizer 180 throws a flag associated withthe recognized event, and event handler 190 associated with the flagcatches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-eventdelivery instructions that deliver event information about a sub-eventwithout activating an event handler. Instead, the sub-event deliveryinstructions deliver event information to event handlers associated withthe series of sub-events or to actively involved views. Event handlersassociated with the series of sub-events or with actively involved viewsreceive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used inapplication 136-1. For example, data updater 176 updates the telephonenumber used in contacts module 137, or stores a video file used in videoplayer module 145. In some embodiments, object updater 177 creates andupdates objects used in application 136-1. For example, object updater176 creates a new user-interface object or updates the position of auser-interface object. GUI updater 178 updates the GUI. For example, GUIupdater 178 prepares display information and sends it to graphics module132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to dataupdater 176, object updater 177, and GUI updater 178. In someembodiments, data updater 176, object updater 177, and GUI updater 178are included in a single module of a respective application 136-1 orapplication view 191. In other embodiments, they are included in two ormore software modules.

It shall be understood that the foregoing discussion regarding eventhandling of user touches on touch-sensitive displays also applies toother forms of user inputs to operate multifunction devices 100 withinput-devices, not all of which are initiated on touch screens, e.g.,coordinating mouse movement and mouse button presses with or withoutsingle or multiple keyboard presses or holds, user movements taps,drags, scrolls, etc., on touch-pads, pen stylus inputs, movement of thedevice, oral instructions, detected eye movements, biometric inputs,and/or any combination thereof, which may be utilized as inputscorresponding to sub-events which define an event to be recognized.

Each of the above identified elements in FIG. 3 may be stored in one ormore of the previously mentioned memory devices. Each of the aboveidentified modules corresponds to a set of instructions for performing afunction described above. The above identified modules or programs(i.e., sets of instructions) need not be implemented as separatesoftware programs, procedures or modules, and thus various subsets ofthese modules may be combined or otherwise re-arranged in variousembodiments. In some embodiments, memory 370 may store a subset of themodules and data structures identified above. Furthermore, memory 370may store additional modules and data structures not described above.

Attention is now directed towards embodiments of user interfaces (“UI”)that may be implemented on portable multifunction device 100.

FIG. 4A illustrates an exemplary user interface for a menu ofapplications on portable multifunction device 100 in accordance withsome embodiments. Similar user interfaces may be implemented on device300. In some embodiments, user interface 400 includes the followingelements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 402 for wireless communication(s),        such as cellular and Wi-Fi signals;    -   Time 404;    -   Bluetooth indicator 405;    -   Battery status indicator 406;    -   Tray 408 with icons for frequently used applications, such as:        -   Phone 138, which may include an indicator 414 of the number            of missed calls or voicemail messages;        -   E-mail client 140, which may include an indicator 410 of the            number of unread e-mails;        -   Browser 147; and        -   Video and music player 152, also referred to as iPod            (trademark of Apple Inc.) module 152; and    -   Icons for other applications, such as:        -   IM 141;        -   Image management 144;        -   Camera 143;        -   Weather 149-1;        -   Stocks 149-2;        -   Workout support 142;        -   Calendar 148;        -   Alarm clock 149-4;        -   Map 154;        -   Notes 153;        -   Settings 412, which provides access to settings for device            100 and its various applications 136;        -   Online video module 155, also referred to as YouTube            (trademark of Google Inc.) module 155;        -   Word processor 384;        -   Drawing 380;        -   Spreadsheet 390; and        -   Presentation 382.

FIG. 4B illustrates an exemplary user interface on a device (e.g.,device 300, FIG. 3) with a touch-sensitive surface 451 (e.g., a tabletor touchpad 355, FIG. 3) that is separate from the display 450 (e.g.,touch screen display 112). Although many of the examples which followwill be given with reference to inputs on touch screen display 112(where the touch sensitive surface and the display are combined), insome embodiments, the device detects inputs on a touch-sensitive surfacethat is separate from the display, as shown in FIG. 4B. In someembodiments the touch sensitive surface (e.g., 451 in FIG. 4B) has aprimary axis (e.g., 452 in FIG. 4B) that corresponds to a primary axis(e.g., 453 in FIG. 4B) on the display (e.g., 450). In accordance withthese embodiments, the device detects contacts (e.g., 460 and 462 inFIG. 4B) with the touch-sensitive surface 451 at locations thatcorrespond to respective locations on the display (e.g., in FIG. 4B, 460corresponds to 468 and 462 corresponds to 470). In this way, user inputs(e.g., contacts 460 and 462, and movements thereof) detected by thedevice on the touch-sensitive surface (e.g., 451 in FIG. 4B) are used bythe device to manipulate the user interface on the display (e.g., 450 inFIG. 4B) of the multifunction device when the touch-sensitive surface isseparate from the display. It should be understood that similar methodsmay be used for other user interfaces described herein.

Additionally, while the following examples are given primarily withreference to finger inputs (e.g., finger contacts, finger tap gestures,finger swipe gestures), it should be understood that, in someembodiments, one or more of the finger inputs are replaced with inputfrom another input device (e.g., a mouse based input or stylus input).For example, a swipe gesture may be replaced with a mouse click (e.g.,instead of a contact) followed by movement of the cursor along the pathof the swipe (e.g., instead of movement of the contact). As anotherexample, a tap gesture may be replaced with a mouse click while thecursor is located over the location of the tap gesture (e.g., instead ofdetection of the contact followed by ceasing to detect the contact).Similarly, when multiple user inputs are simultaneously detected, itshould be understood that multiple computer mice may be usedsimultaneously, or a mouse and finger contacts may be usedsimultaneously.

USER INTERFACES AND ASSOCIATED PROCESSES

Attention is now directed towards embodiments of user interfaces (“UI”)and associated processes that may be implemented on an electronic devicewith a display and a touch-sensitive surface, such as device 300 orportable multifunction device 100.

FIG. 5A illustrates document 500 displayed on touch screen 112 of device100. Document 500 may be displayed in the user interface of anapplication (e.g., a word processing application, a presentationapplication, a spreadsheet application, etc.). The application userinterface in which document 500 is displayed may include toolbar 510 and“documents” button 512 for navigating to, if any, other documents. Insome embodiments, document 500 is displayed in a document viewing ornavigating mode.

Document 500 includes content, such as text 502, images, objects,tables, charts, and so on. Text 502 has a respective font size. In someembodiments, text 502 includes multiple portions with respective,different font sizes. Document 500 has a predefined page layout; thecontent in document 500 is laid out in a predefined way and the layoutis not affected by changes in the magnification level at which document500 is displayed on touch screen 112.

Document 500 is displayed at a first magnification level. For example,as shown in FIG. 5A, the first magnification level may be one thatcorresponds to fitting a whole page of document 500 on display 112.Document 500 may also be displayed at a larger or smaller magnification(e.g., in response to user input). Text 502, for the same font size, hasa text display size on screen that varies with the magnification level.Thus, text 502 has a first display size at the “fit whole page”magnification level. The text display size is the size of the text as itappears on the display of a device (e.g., touch screen 112 of device100), as opposed to the font size, which is the size of the text as itwould appear if printed out on physical media (e.g., paper).

In some embodiments, the magnification level is expressed as apercentage (e.g., 100%, 200%, 50%, etc.). The fit whole pagemagnification level described above corresponds to a magnification levelpercentage that achieves the fitting of a whole page onto display 112.

Gesture 504 is detected at a location on touch screen 112 correspondingto a location on document 500. In some embodiments, gesture 504 is asingle tap gesture. The location of gesture 504 indicates insertionpoint 506 in text 502. Insertion point 506 is proximate to text portion508 of text 502.

FIG. 5B shows, alternatively, gesture 514 detected at a location ontouch screen 112 corresponding to a location on document 500. In someembodiments, gesture 514 includes a tap and hold of a finger contact(i.e., finger makes contact on touch screen 112 and maintains contactwith touch screen 112, followed by a later liftoff of the contact). Inresponse to the detection of gesture 514, loupe 516 is displayed,showing a magnified view of text portion 508 and insertion point marker518 indicating an insertion point at a location in text 502 thatcorresponds to the location of gesture 514. While gesture 514 is active(i.e., contact with touch screen 112 is maintained), insertion pointmarker 518 may be moved across document 500 (e.g., by moving the fingeracross touch screen 112) and loupe 516 follows the movement of insertionpoint marker to show a magnified view of the text in proximity toinsertion point marker 518.

In response to the detection of gesture 504 or 514 and the completion ofthe respective gesture (e.g., when the finger contact of gesture 504 or514 is lifted up from touch screen 112), portion 520 of document 500 isdisplayed in document editing mode, as shown in FIG. 5C. While indocument editing mode, document 500 (including portion 520) is displayedat a second magnification level that is different from the firstmagnification level. Document portion 520 includes text portion 508. Insome embodiments, the second magnification level is a magnificationlevel at which text portion 508 is displayed on touch screen 112 at atext display size that is comfortable for reading. For example, if textportion 508 has a font size whose text display size at 100%magnification is not comfortable for reading on touch screen 112, textportion 508 may be displayed, when in document editing mode, at 200%magnification.

Insertion point marker 518 is displayed at the insertion point (e.g.,insertion point 506), and text portion 508 is proximate (e.g., adjacent)to insertion point marker 518. In some embodiments, insertion pointmarker 518 is a text cursor.

Document portion 520 is displayed such that the predefined layout ofdocument 500 is maintained; text 502, including text portion 508 is notre-flowed, re-wrapped, or the like. While in document editing mode,document 500 is scrollable (e.g., in response to swipe or flick gestureson touch screen 112).

While document portion 520 is displayed m document editing mode,keyboard 521 is also displayed, and “documents” button in toolbar 510 isreplaced by “done” button 522. A user may enter text into document 500by typing on keyboard 521, and confirm completion of editing of document500 by performing a gesture (e.g., a tap gesture) on “done” button 522.When “done” button 522 is activated by performance of a gesture on“done” button 522, the document editing mode ends and a document viewingmode resumes. For example, FIG. 5D shows gesture 524 detected on touchscreen 112 at a location corresponding on “done” button 522 (gesture 524may be said to be detected on “done” button 522).

In response to the detection of gesture 524, document 500, including therevisions entered and confirmed in document editing mode, is displayedat the fit whole page magnification level and in a document viewingmode, as shown in FIG. 5E. “Done” button 522 is replaced by “documents”button 512 in toolbar 510.

FIG. 5F shows document 500, with text 502, displayed in document viewingmode, along with toolbar 510 and “documents” button 512. Document 500 isdisplayed at fit whole page magnification; text 502 is displayed at atext display size corresponding to the fit whole page magnificationlevel.

Gesture 526 is detected at a location on touch screen 112 correspondingto a location on document 500. In some embodiments, gesture 526 is asingle tap gesture. The location of gesture 526 indicates insertionpoint 506 in text 502. Insertion point 506 is proximate to text portion508 of text 502.

In response to the detection of gesture 526, document portion 520 ofdocument 500 is displayed in document editing mode, as shown in FIG. 5G.Document portion 520 includes text portion 508. Document portion 520 isdisplayed at a magnification level such that text portion 508 isdisplayed at a default target text display size. Keyboard 521 is alsodisplayed, and “documents” button 512 is replaced by “done” button 522.Insertion point marker 518 is displayed to mark insertion point 506.

Gesture S34 is detected on touch screen 112. Gesture 534 is a gesture toadjust the magnification level at which document portion 520 isdisplayed. In some embodiments, gesture 534 is a depinch gesture, withcontacts 534-A and 534-B moving apart. In response to the detection ofgesture 534, document portion 520 is displayed, while remaining indocument editing mode, at a user-adjusted magnification level, as shownin FIG. 5H, which in this case is larger than the magnification level asshown in FIG. 5G. Accordingly, text portion 520 is displayed at auser-adjusted text display size, which in this case is larger than thedefault target text display size as shown in FIG. 5G. The user-adjustedtext display size is stored by device 100.

While text portion 508 is displayed at the user-adjusted text displaysize, gesture 536 is detected on “done” button 522, as shown in FIG. 5H.In response to the detection of gesture 536 on “done” button 522,document 500, including the revisions entered and confirmed in documentediting mode, is displayed at the fit whole page magnification level andin a document viewing mode, as shown in FIG. 5I “Done” button 522 isreplaced by “documents” button 512 in toolbar 510.

In FIG. 5I, while document 500 is displayed in document viewing mode andat the fit whole page magnification level, gesture 536 is detected at alocation on touch screen 112 corresponding to a location on document500. In some embodiments, gesture 536 is a single tap gesture. Thelocation of gesture 536 indicates insertion point 538 in text 502.Insertion point 538 is proximate to text portion 540 of text 502.

In response to the detection of gesture 536, document portion 541 ofdocument 500, which includes text portion 540, is displayed in documentediting mode, as shown in FIG. 5J. Document portion 541 is displayed ata magnification level such that text portion 540 is displayed at theuser-adjusted text display size that was stored previously. Insertionpoint marker 518 is displayed to mark insertion point 538. Despitedocument portion 541 being a different portion of document 500 thandocument portion 520 (and text portion 540 being different from textportion 508), document portion 541 is displayed at a magnification levelsuch that text portion 540 is displayed at the user-adjusted textdisplay size.

FIG. 5K illustrates document 542, which includes text 543, beingdisplayed in document viewing mode on touch screen 112. Document 542includes document portions 544 and 546. The text (a portion of text 543)in document portion 544 and the text (another portion of text 543) indocument portion 546 have different font sizes. At a given magnificationlevel at which document 542 is displayed, the text display size of textin document portion 544 is larger than the text display size of text indocument portion 546.

Gesture 548 is detected at a location on touch screen 112 correspondingto a location on document 542. In some embodiments, gesture 548 is asingle tap gesture. The location of gesture 548 indicates insertionpoint 550 in text 543. Insertion point 550 is proximate to text portion552 of text 543. Text portion 552 is located in document portion 546.

In response to the detection of gesture 548, document portion 546 isdisplayed in document editing mode, as shown in FIG. 5L. Documentportion 546 is displayed at a certain magnification level. Accordingly,text portion 552 is displayed at a target text display size. Insertionpoint marker 518 is displayed to mark insertion point 550. Alsodisplayed is keyboard 521.

FIG. 5M shows document portion 544, which includes text portion 556 oftext 543, displayed on touch screen 112 in document editing mode.Document portion 544 may be reached from document portion 546 asdisplayed in FIG. 5L by scrolling document 542 (e.g., using swipegestures). Alternatively, document portion 544 may be reached fromdocument portion 546 as displayed in FIG. 5L by dragging insertionmarker 518 from document portion 546 to document portion 544 while indocument editing mode. Document portion 544 is displayed at the samemagnification level as document portion 546 is displayed in FIG. 5L.Text portion 556 is displayed at a larger text display size than textportion 552 is displayed in FIG. 5L. Text portion 556 has a larger fontsize than text portion 552 and thus has a larger text display size forthe same magnification level.

Gesture 554 is detected at a location on touch screen 112 correspondingto a location in document portion 544. In some embodiments, gesture 554is a single tap gesture. The location of gesture 554 indicates insertionpoint 555 in text 544. Insertion point 555 is proximate to text portion556 of text 544.

In response to the detection of gesture 554, as shown in FIG. 5N,document portion 544 is displayed at a lower magnification level thanthat shown in FIG. 5M. At this lower magnification level, text portion556 is displayed at the same text display size as text portion 552 isdisplayed in FIG. 5L; the magnification level of the document is changedsuch that text of different font sizes are displayed at the same textdisplay size as the user navigates from text of one font size to text ofa different font size.

FIG. 5O illustrates a portion of document 558 being displayed, indocument editing mode, at a certain magnification level. Text indocument 558 is displayed at a certain text display size. Text 562 isselected, as indicated by content selection range 560. Also displayedare selection options menu 565 for manipulating the selected text 562,and content selection, handles 564-A and 564-B for adjusting contentselection range 560. Gesture 566 is detected on handle 564-B, dragginghandle 564-B in a direction that increases content selection range 560(e.g., downward in FIG. 5O).

In response to the detection of gesture 566, selection range 560 isenlarged, as shown in FIG. 5P. In some embodiments, loupe 567, whichshows a magnified view of text at the end of selection range 560 ashandle 564-B is moved, is displayed.

With the enlarged content selection range 560, selected text 562includes more text than is shown in FIG. 5O. Some of selected text 562is not displayed in FIG. 5O.

FIG. 5Q illustrates gesture 566 ceasing to be detected on touch screen112, while selection range 560 includes an end of a paragraph indocument 558. With the ceasing (lift off) of gesture 566, adjustment ofcontent selection range 560 is completed. In response to detectingcompletion of gesture 566, the magnification level at which document 558is displayed is changed, as shown in FIG. 5R. The new magnificationlevel is chosen so that the entirety of selected text 562 in contentselection range 560 is displayed on touch screen 112, rather thanshowing just some of selected text 562 because the magnification levelis too high. For example, document 558 may be displayed at a fit wholepage magnification level, as shown in FIG. 5R, or a fit page widthmagnification level.

Also shown in FIG. 5R, content selection range 560 is extended so thatselected text 562 includes an entire paragraph. Also displayed areparagraph selection options menu 569 for manipulating the selectedparagraph, and handles 564-A and 564-B for adjusting selection range560. As shown in FIG. 5R, handles 564-A and 564-B may be dragged toadjust selection range 560 to select more paragraphs or less paragraphs;a paragraph becomes the unit of text selection, as opposed to a smallerunit such as a character or a word.

In FIG. 5R, gesture 568 is detected on handle 564-B, which drags handle564-B downward, toward another paragraph of text in document 558. Inresponse to the detection of gesture 568, selection range 560 isextended by a paragraph, and selected text 562 includes anotherparagraph, as shown in FIG. 5S.

FIG. 5T shows document 570 displayed in document viewing mode on touchscreen 112. Document 570 includes objects 572 and 576. In someembodiments, an object is a shape, image, or other graphical object.Object 572 includes editable text 574, and object 576 does not includeeditable text.

When a gesture is detected on object 576 (e.g., gesture 580, which maybe a single tap gesture, on object 576, FIG. 5T), object 576 isdisplayed in document editing mode, at a magnification level thatachieves a particular object display size, as shown in FIG. 5U. Theobject display size is the size of the object as is appears on thedisplay. In some embodiments, that particular object display size is apredefined size with respect to touch screen 112. For example, thepredefined size may be a size that fits the entire object 576 onto touchscreen 112.

In contrast, when a gesture is detected on object 572 (e.g., gesture582, which may be a single tap gesture, FIG. 5T), object 572 isdisplayed in document editing mode, at a magnification level thatachieves a particular text display size for text 574, as shown in FIG.5V. This magnification level may be selected without reference to thesize of object 572. In some embodiments, that particular text displaysize is a default text display size or a previously-stored user-adjustedtext display size. Thus, when a gesture (e.g., a single tap gesture) isdetected on an object, if the object includes editable text, the newmagnification level accommodates the text, and if the object does notinclude editable text, the new magnification level accommodates theobject.

FIG. 5W illustrates document 584 being displayed, in document viewingmode, on touch screen 112. Document 584 is a spreadsheet document andincludes worksheet 591. Worksheet 591 includes one or more rows and oneor more columns. Document 582 is displayed at some magnification level.Also displayed are toolbar 586 and “spreadsheets” 588 for navigating toother spreadsheet documents, similar to “documents” button 512.

Gesture 590, for changing the magnification level of document 584, isdetected on touch screen 112. Gesture 590 includes contacts 590-A and590-B moving apart (i.e., gesture 590 is a depinch gesture). In responseto the detection of gesture 590, document 584 is displayed, still in thedocument vlewmg mode, at a user-adjusted magnification level, as shownin FIG. 5X.

Gesture 592 is detected on touch screen 112, in proximity of cell 594 inworksheet 591. In some embodiments, gesture 592 is a double tap gesture.Cell 594 becomes the insertion point. In response to the detection ofgesture 592, document 584 is displayed in a document editing mode, asshown in FIG. 5Y. Document 584 is displayed at a magnification leveldifferent from the user-adjusted magnification level. Cell 594, as thecell that is in proximity to gesture 592, becomes an editable cell andin focus (e.g., centered) and is highlighted by cell insertion pointmarker 593. Also displayed are keypad 595, edit field 596 showing thecurrent contents of cell 594, and edit complete button 597. A user mayenter edits into the contents of cell 594 using keypad 595, and theedits are reflected in edit field 596.

When editing is completed, a user activates edit complete button 597with a gesture. For example, gesture 598 is detected on edit completebutton 597, as shown in FIG. 5Z. In some embodiments, gesture 598 is asingle tap gesture. In response to the detection of gesture 598 on editcomplete button 597, document 584 is displayed at the user-adjustedmagnification level (the same level as in FIG. 5X), as shown in FIG.5AA. Edit field 596 ceases to be displayed, and in worksheet 591, cellselection marker 599 is displayed instead of cell insertion point marker593.

FIGS. 6A-6E are flow diagrams illustrating a method 600 of navigatingand editing an electronic document in accordance with some embodiments.The method 600 is performed at an electronic device (e.g., device 300,FIG. 3, or portable multifunction device 100, FIG. 1) with a displayand, typically, a touch-sensitive surface. In some embodiments, thedisplay is a touch screen display and the touch-sensitive surface is onthe display. In some embodiments, the display is separate from thetouch-sensitive surface. Some operations in method 600 may be combinedand/or the order of some operations may be changed.

As described below, the method 600 provides an intuitive way toautomatically zoom in on a user-specified insertion point when enteringa document editing mode and display the text at the insertion point at atarget text display size for easy viewing and editing. The methodreduces the cognitive burden on a user when navigating and editing anelectronic document, thereby creating a more efficient human-machineinterface. For battery-operated electronic devices, enabling a user tozoom in on content in a document faster and more efficiently conservespower and increases the time between battery charges.

The device displays at least a portion of an electronic document with apredefined page layout at a first magnification level on the display(602). In other words, the electronic document has a fixed page layoutand the text does not “reflow” as the magnification level of thedocument is changed. For example, in FIG. 5A, document 500 withpredefined page layout is displayed on touch screen 112. In FIG. 5A,document 500 is displayed at the fit whole page magnification level.

In some embodiments, the predefined page layout is a multi-page layoutand the document has content that is associated with a plurality of thepages (e.g., the electronic document is a word processor document,presentation document, pdf, etc.) (604). For example, document 500 mayhave one or more pages in addition to the one displayed in FIG. 5A.

In some embodiments, the predefined page layout is a table with aplurality of rows and a plurality of columns (e.g., the electronicdocument is a spreadsheet document, etc.) (606).

The device detects a first input indicating a first insertion point inthe document, where the first insertion point is proximate to (e.g.,adjacent to) a first portion of text in the document (608). The firstportion of text is typically a word or character adjacent to the firstinsertion point that has a predefined font size (e.g., a font sizespecified by the document). For example, in FIG. 5A gesture 504 isdetected. The location of gesture 504 indicates the insertion point 506.In some embodiments, the gesture is a finger gesture (e.g., a tapgesture) that has a contact area and the centroid of the contact area(or a point offset from the centroid of the contact area) is used tolocate the insertion point. Insertion point 506 is proximate to textportion 508.

It should be understood that, as used herein, the term “insertion point”refers to a location within the document that may also used as alocation for displaying an insertion point marker, such as a text cursoror highlighted word.

In response to detecting the first input (610), the device selects asecond magnification level different from the first magnification level,where the second magnification level is selected so as to display thefirst portion of text at a target text display size (612); and, whilemaintaining the predefined page layout of the document, the devicedisplays, at the second magnification level, a portion of the documentthat includes the first portion of text (614). For example, in FIGS. 5Athru 5C, in response to the detection of gesture 504 (FIG. 5A) orgesture 514 (FIG. 5B), document portion 520, which includes text portion508, is displayed at a larger magnification level, where the largermagnification level is one that is selected so that text portion 508 isdisplayed at a text display size that is comfortable for reading.

In other words, a magnification level is selected such that text isdisplayed at a target text display size that has been determined to be acomfortable reading size (e.g., 17 pt or some other predefined textdisplay size).

It should be understood that the target text display size may be eithera predefined target text display size or a user-adjusted target textdisplay size, as described below in greater detail with reference tomethod 700 and FIGS. 7A-7B.

It should be understood that, as used in the specification and claims,“text display size” is different from “font size.” In particular, asused herein, the “font size” of the text corresponds to a physicaldimension of the text as it would appear if the document were to beprinted out. In contrast, “text display size” corresponds to a dimensionof the text as it appears on the display of the electronic device and isnot necessarily the physical dimension of the text as it would appearwhen printed. Thus, the text display size of a word may be substantiallylarger or substantially smaller than the font size, depending on themagnification level at which the document is displayed. For example, aword with font size of 12 pt in a document could be displayed at a textdisplay size of 24 pt by displaying the document at a 200% magnificationlevel.

In some embodiments, displaying the portion of the document at thesecond magnification level includes displaying an animation of thedocument zooming from the first magnification level to the secondmagnification level (616). For example, there may be an animatedtransition from the magnification level shown in FIG. 5A to themagnification level as shown in FIG. 5C.

In some embodiments, in response to detecting the first input, thedevice performs an operation selected from the set consisting of:placing a text cursor at the first insertion point, selecting a cell ofa spreadsheet proximate to the first insertion point for editing, andhighlighting text proximate to the first insertion point (618). Forexample, in response to the detection of gesture 504 (FIG. 5A),insertion point marker 518 is inserted at insertion point 506 (FIG. 5C).

In some embodiments, in response to detecting the first input, thedevice scrolls the document so that the first insertion point is in acentral region of a displayed portion of the document (620). In someembodiments, the document is scrolled in one dimension (e.g.,horizontally or vertically). In some embodiments, the document isscrolled or translated in two dimensions (e.g., horizontally andvertically). For example, in FIG. 5C, insertion point marker 518(marking insertion point 506) is approximately centered in the displayedpart of document portion 520. Scrolling of document 500 may be needed,when transitioning from the magnification level shown in FIG. 5A to themagnification level shown in FIG. 5C, to achieve the centering.

In some embodiments, the electronic device includes a touch-sensitivesurface, and the first input is detected on the touch-sensitive surface(622). In some embodiments, the touch-sensitive surface is separate fromthe display. In some embodiments, the touch-sensitive surface and thedisplay are combined as a touchscreen display. For example, display 112on device 100 is a touch screen, and gesture 504 is detected on touchscreen 112.

In some embodiments, the first input is a single tap on thetouch-sensitive surface (624). For example, gesture 504 (FIG. 5A) may bea single tap gesture.

In some embodiments, the electronic device includes a touch-sensitivesurface, and the first input includes detecting a contact on thetouch-sensitive surface, detecting movement of the contact on thetouch-sensitive surface, and ceasing to detect the contact on thetouch-sensitive surface (626). For example, in FIG. 5B, gesture 514includes a contact on touch screen 112, any movement as needed to moveinsertion point marker 518 to the desired insertion point location, andliftoff of the contact from touch screen 112.

In some embodiments, while detecting movement of the contact on thetouch-sensitive surface, the device displays a magnified portion of thedocument corresponding to a current location of the contact on thetouch-sensitive surface, where the first insertion point is selectedbased on a position of the contact on the touch-sensitive surface whenthe device ceases to detect the contact on the touch-sensitive surface(628). In some embodiments, the magnified portion of the document hasthe appearance of a loupe and enables more accurate selection of thefirst insertion point. For example, in FIG. 5B, loupe 516 is displayed.Loupe 516 shows a magnified view of text 508 around insertion pointmarker 518, which is located at a location in document 500 correspondingto the location of the contact of gesture 514. The location of insertionpoint marker 518 is confirmed when the contact of gesture 514 lifts offfrom touch screen 112.

In some embodiments, in response to detecting the first input, thedevice enters a document-editing mode (630). For example, in FIG. 5C, inresponse to gesture 504 or 514, document portion 520 is displayed indocument editing mode. Keyboard 521 is displayed, and “documents” button512 is replaced by “done” button 522. Thus, a single input (e.g., a tapgesture or a tap and hold gesture) results in: entering edit mode,placing a text cursor, zooming to a different magnification level with acomfortable text display size, scrolling the document to place theinsertion point in a central region of the display, and displaying asoft keyboard.

In some embodiments, the electronic device enters the document-editingmode in response to detecting an end of the first input (e.g., when thedisplay is a touchscreen display, detecting the end of the input istypically detecting liftoff of a contact from the touchscreen display)(632). For example, document 500 is displayed in document editing mode(as in FIG. 5C) in response to the end of gesture 504 or 514.

In some embodiments, in response to detecting the first input, thedevice displays a soft keyboard on the display (634). For example, inresponse to gesture 504, along with the display of document 500 indocument editing mode, keyboard 521 is displayed (FIG. 5C).

In some embodiments, while in the document-editing mode, the deviceedits text of the document in response to user inputs (636). Forexample, in FIG. 5C-5D, text portion 508 may be edited in response touser typing on keyboard 521.

In some embodiments, the document is one of a plurality of documents(638). Prior to entering the document-editing mode, the device displaysa navigation affordance (e.g., documents button) for navigating betweendifferent documents in a set of documents (640). After entering thedocument-editing mode, the device replaces the navigation affordancewith an exit affordance (e.g., done button) for exiting thedocument-editing mode (642). For example, In FIG. 5A, “documents” button512 is displayed. In FIG. 5C, when document 500 is displayed in documentediting mode, “documents” button 512 is replaced by “done” button 522.

In some embodiments, the device receives a request to exit thedocument-editing mode (644); and, in response to receiving the requestto exit the document-editing mode (646), exits the document-editing mode(648) and displays the document at the first magnification level. (e.g.,returns to prior magnification level) (650). For example, in FIG. 5D,gesture 524 is detected on “done” button 522. In response to thedetection of gesture 524 on “done” button 522, document 500 is displayedin document viewing mode at fit whole page magnification (as shown inFIG. 5E), which is the same magnification level as in FIG. 5A.

In some embodiments, the device receives a request to exit thedocument-editing mode (652); and, in response to receiving the requestto exit the document-editing mode (654), exits the document-editing mode(656) and displays the document at a third magnification level thatcorresponds to a predefined document magnification level different fromthe first magnification level (e.g., a page width magnification level)(658). For example, in FIG. 5D, gesture 524 is detected on “done” button522. In response to the detection of gesture 524 on “done” button 522,document 500 may be displayed at a magnification level different thanthe magnification level shown in FIG. 5A (not shown).

In some embodiments, while in the document-editing mode, the devicescrolls the document in response to detecting inputs from a user (660);and, after exiting the document-editing mode, redisplays the document asit appeared when the first input was detected (662). In other words, thedocument is scrolled and zoomed so as to reposition the document at thesame magnification level and scroll position that it was displayed atprior to entering the edit mode. It should be understood that thedocument may be scrolled in one or two dimensions while in edit mode.For example, in FIG. 5C, document 500 is scrollable while in documentediting mode. After exiting document editing mode in response todetection of gesture 524, document 500 is displayed at the samemagnification level as when gesture 504 is detected in FIG. 5A.

In some embodiments, the target text display size at which the firstportion of text is displayed in response to detecting the first input isa default target text display size (664). While displaying the portionof the document that includes the first portion of text at the secondmagnification level, the device detects a second input corresponding toa request to display a portion of the document at a third magnificationlevel different from the second magnification level (666). In responseto detecting the second input (668), the device displays the portion ofthe document at the third magnification level (670) and stores auser-adjusted target text display size corresponding to a text displaysize of the first portion of text at the third magnification level(672), where the user-adjusted target text display size is differentfrom the default target text display size. After storing theuser-adjusted target text display size (674), the device detects a thirdinput indicating a second insertion point in the document, where thesecond insertion point is proximate to a second portion of text in thedocument (676); and in response to detecting the third input, displaysthe document at a respective magnification level such that the secondportion of text is displayed at the user-adjusted target text displaysize (678). For example, in FIGS. 5C and 5G, text portion 508 isdisplayed at a text display size that may be a default text display sizeas a result of document portion 520 being displayed at the secondmagnification level. In FIG. 5G, gesture 534 to adjust the magnificationlevel is detected. In response to the detection of gesture 534, documentportion 520 is displayed at a user-adjusted magnification level (asshown in FIG. 5H), and a text display size corresponding to theuser-adjusted magnification level is stored. Subsequently, gesture 536(Figure SI) indicating insertion point 538 is detected. In response tothe detection of gesture 536, document portion 541 is displayed at theuser-adjusted magnification level so that text portion 540 is displayedat the stored text display size (instead of the prior default textdisplay size in FIGS. 5A and 5G), as shown in FIG. 5J.

In some embodiments, the first portion of text has a first font size(680). While displaying the portion of the document that includes thefirst portion of text at the second magnification level, the devicedetects a second input indicating a second insertion point in thedocument (682), where the second insertion point is proximate to asecond portion of text in the document, and the second portion of texthas a second font size different from the first font size. In responseto detecting the second input (684), the device selects a thirdmagnification level different from the second magnification level (686),where the third magnification level is selected so as to display thesecond portion of text at the target text display size, and displays aportion of the document at the third magnification level (688). Forexample, text portion 508 has a font size, and is displayed at a textdisplay size (FIG. 5C). A gesture indicating another insertion pointproximate to a text portion with a different font size, analogous togesture 554 (FIG. 5M), may be detected. In response to the gesture, textin the text portion with the different font size is displayed at acertain magnification level so that that text is displayed at a sametext display size as text portion 508.

In some embodiments, after displaying the portion of the document thatincludes the first portion of text at the second magnification level(690), the device detects a content selection input (692). In responseto detecting the content selection input (694), the device identifies aselected portion of the document in accordance with the contentselection input (696), and in accordance with a determination that theselected portion of the document includes content that is outside of acurrently displayed portion of the document, the device adjusts displayof the document so that the entire selected portion of the document isdisplayed on the display (698). For example, a content selection inputsimilar to gesture 566 (FIG. 5O) on content selection handle 564-B maybe detected. In response to the detection of gesture 566, text indocument 500 may be selected. If the selected text includes portionoutside of a currently displayed portion, the magnification level ofdocument 500 may be adjusted to display the entire selected text.

It should be understood that the particular order in which theoperations in FIGS. 6A-6E have been described is merely exemplary and isnot intended to indicate that the described order is the only order inwhich the operations could be performed. One of ordinary skill in theart would recognize various ways to reorder the operations describedherein. Additionally, it should be noted that details of other processesdescribed herein with respect to methods 700, 800, 900, 1000, and 1100(e.g., FIGS. 7A-7B, 8A-8B, 9A-9B, 10, and 11A-11B, respectively) arealso applicable in an analogous manner to method 600 described abovewith respect to FIGS. 6A-6E. For example, the electronic document,insertion point and various magnification levels described above withreference to method 600 may have one or more of the characteristics ofthe electronic document, insertion point and various magnificationlevels described herein with reference to methods 700, 800, 900, 1000,and 1100. For brevity, these details are not repeated here.

FIGS. 7A-7B are flow diagrams illustrating a method 700 of navigatingand editing an electronic document in accordance with some embodiments.The method 700 is performed at an electronic device (e.g., device 300,FIG. 3, or portable multifunction device 100, FIG. 1) with a display anda, typically, touch-sensitive surface. In some embodiments, the displayis a touch screen display and the touch-sensitive surface is on thedisplay. In some embodiments, the display is separate from thetouch-sensitive surface. Some operations in method 700 may be combinedand/or the order of some operations may be changed.

As described below, the method 700 provides an intuitive way to modifythe target text display size from a default value to a user-adjustedvalue. The method reduces the cognitive burden on a user when navigatingand editing an electronic document, thereby creating a more efficienthuman-machine interface. For battery-operated electronic devices,enabling a user to zoom in on content in a document faster and moreefficiently conserves power and increases the time between batterycharges.

The device displays at least a portion of an electronic document at afirst magnification level on the display (702). For example, in FIG. 5F,document 500 is displayed at a fit whole page magnification level.

In some embodiments, the document has a predefined page layout and thepredefined page layout is maintained while displaying the document atdifferent magnification levels (704).

The device detects a first input indicating a first insertion point inthe document, wherein the first insertion point is proximate to a firstportion of text in the document (706). For example, in FIG. 5F, gesture526 is detected. The location of gesture 526 indicates insertion point506, which is proximate to text portion 508.

In response to detecting the first input (708), the device selects asecond magnification level different from the first magnification level,where the second magnification level is selected so as to display thefirst portion of text at a default target text display size (710), anddisplays a portion of the document at the second magnification level(714). For example, in FIG. 5G, in response to detecting gesture 526,document portion 520 is displayed at a different magnification levelfrom the fit whole page magnification level shown in FIG. 5F. Thedifferent magnification level is one that is selected by device 100 suchthat text portion 508 (adjacent to the insertion point) is displayed ata default target text display size.

In some embodiments, the default target text display size is apredefined value in the range 10 pt-24 pt (712).

The device detects a second input corresponding to a request to displaya portion of the document at a third magnification level different fromthe second magnification level (716). For example, in FIG. 5G, depinchgesture 534 to change the magnification level is detected.

In response to detecting the second input (718), the device displays theportion of the document at the third magnification level (720), andstores a user-adjusted target text display size corresponding to a textdisplay size of the first portion of text (e.g., the text adjacent tothe first insertion point) at the third magnification level, where theuser-adjusted target text display size is different from the defaulttarget text display size (722). For example, in response to thedetection of gesture 534, document portion 520 is displayed at yetanother magnification level (FIG. 5H). At this user-adjustedmagnification level, text portion 508 has a particular text displaysize. This text display size is stored as a user-adjusted target textdisplay size.

In some embodiments, the user-adjusted target text display size is onlystored when the text display size of the first portion of text meetspredefined text display size criteria (e.g., in accordance with adetermination that the text display size of the first portion of text iswithin a range of values that are “allowable” target text displaysizes). In other words, the input is ignored for the purposes of storinga user-adjusted target display size if the user zooms to a magnificationlevel at which text is either too large (e.g., greater than 72 pt) ortoo small (e.g., smaller than 10 pt) for a typical user to comfortablyread, because the user is likely zooming the document for some purposeother than editing text proximate to the insertion point.

After storing the user-adjusted target text display size (724), thedevice detects a third input indicating a second insertion point in thedocument, where the second insertion point is proximate to a secondportion of text in the document (726), and, in response to detecting thethird input, displays the document at a respective magnification levelsuch that the second portion of text is displayed at the user-adjustedtarget text display size (730). It should be understood that the firstportion of text may be the same as or different from the second portionof text. For example, in FIG. 5I, gesture 536 is detected. Gesture 536indicates insertion point 538, which is proximate to text portion 540.In response to the detecting gesture 536, document portion 541 isdisplayed at a magnification level such that text portion 540 isdisplayed at the stored user-adjusted target text display size (FIG.5J).

It should be understood that this process could be repeated any numberof times to set a new user-adjusted target text display size. However,typically, a user will determine a preferred target text display sizeand thus the user will not need to continually adjust the user-adjustedtarget text display size. Rather, the user will find that the targettext display size used for the whole document (or set of documents) isthe user's preferred target text display size, which will improve userefficiency and enhance user productivity.

In some embodiments, the user-adjusted target text display size isignored or discarded when the user-adjusted target text display size isnot within predefined text display size criteria. Optionally, thepredefined text display size criteria include an upper bound (e.g., atext display size between 48 pt-80 pt) and a lower bound of (e.g., atext display size between 10 pt-18 pt). Thus, in these embodiments, whenthe text display size of the first portion of text at the thirdmagnification level is outside of the predefined text display sizecriteria (e.g., above the upper bound or below the lower bound), thedevice continues to use the default target text display size or the lastuser-adjusted target text display size that was within the predefinedtext display size criteria. For example, if a user zooms out to displaya whole page (e.g., at 4 pt text display size) of a document in adocument-editing mode immediately prior to exiting the document-editingmode, the device either reverts to the default target text display size(e.g., 17 pt) or a prior user-adjusted target text display size (e.g.,15 pt). Thus, in this example, when the device re-entersdocument-editing mode, the device displays the document at a respectivemagnification level such that the respective portion of text iscomfortably readable (e.g., 17 pt or 15 pt rather than 4 pt).

In some embodiments, the first portion of text is different from thesecond portion of text (728). For example, text portion 508 (FIG. 5H) isdifferent from text portion 540 (FIG. 5J). In other words, theuser-adjusted target text display size may be used as a target textdisplay size for many different locations within the same document.

In some embodiments, the device uses the user-adjusted target textdisplay size as a target display size for a plurality of differentdocuments accessible by the device (736). In other words, theuser-adjusted target text display size may also be used as a target textdisplay size for many different documents on the device.

In some embodiments, the respective magnification level is the same asthe third magnification level if the second portion of text has a samefont size as the first portion of text (732). In other words, when thecursor moves between text with the same font size, the document is notzoomed to a different magnification level.

In some embodiments, the respective magnification level is differentfrom the third magnification level if the second portion of text has adifferent font size from a font size of the first portion of text (734).In other words, when the cursor moves between text with different fontsizes, the document is zoomed to a different magnification level.

In some embodiments, after storing the user-adjusted target text displaysize and prior to detecting a third input indicating the respectiveinsertion point in the document, the device exits a document-editingmode and displays the document at the first magnification level (738).For example, in FIG. 5H, after the user-adjusted target text displaysize is stored, gesture 536 is detected on “done” button 522. Inresponse to the detection of gesture 536, document 500 is displayedagain at the magnification level in FIG. 5F, as shown in FIG. 5I.

It should be understood that the particular order in which theoperations in FIGS. 7A-7B have been described is merely exemplary and isnot intended to indicate that the described order is the only order inwhich the operations could be performed. One of ordinary skill in theart would recognize various ways to reorder the operations describedherein. Additionally, it should be noted that details of other processesdescribed herein with respect to methods 600, 800, 900, 1000, and 1100(e.g., FIGS. 6A-6E, 8A-8B, 9A-9B, 10, and 11A-11B, respectively) arealso applicable in an analogous manner to method 700 described abovewith respect to FIGS. 7A-7B. For example, the electronic document,insertion point and various magnification levels described above withreference to method 700 may have one or more of the characteristics ofthe electronic document, insertion point and various magnificationlevels described herein with reference to methods 600, 800, 900, 1000,and 1100. For brevity, these details are not repeated here.

FIGS. 8A-8B are flow diagrams illustrating a method 800 of navigatingand editing an electronic document in accordance with some embodiments.The method 800 is performed at an electronic device (e.g., device 300,FIG. 3, or portable multifunction device 100, FIG. 1) with a display,typically, and a touch-sensitive surface. In some embodiments, thedisplay is a touch screen display and the touch-sensitive surface is onthe display. In some embodiments, the display is separate from thetouch-sensitive surface. Some operations in method 800 may be combinedand/or the order of some operations may be changed.

As described below, the method 800 provides an intuitive way toautomatically adjust the display magnification to maintain a target textdisplay size as the insertion point is moved between areas in a documentwith different font sizes. The method reduces the cognitive burden on auser when navigating and editing an electronic document, therebycreating a more efficient human-machine interface. For battery-operatedelectronic devices, enabling a user to zoom in on content in a documentfaster and more efficiently conserves power and increases the timebetween battery charges.

The device displays at least a portion of an electronic document at afirst magnification level on the display (802). For example, in FIG. 5K,document 542 is displayed at some magnification level on touch screen112.

In some embodiments, the electronic document has a predefined pagelayout and the predefined page layout is maintained while displaying thedocument at different magnification levels (804). For example, document542 has a predefined layout that is maintained across differentmagnification levels.

The device detects a first input indicating a first insertion point inthe document (806), where the first insertion point is proximate to afirst portion of text in the document, the first portion of text havinga first font size. Alternatively, the first font size is a font size atthe insertion point (e.g., when there is an insertion point marker suchas a text cursor, the first font size is a font size that would be usedfor text entered at the text cursor). For example, in FIG. 5K, gesture548 is detected. The location of gesture 548 indicates insertion point550, which is in proximity to text portion 552.

In response to detecting the first input (808), the device selects asecond magnification level different from the first magnification level,where the second magnification level is selected so as to display thefirst portion of text at a target text display size (810); and displaysa portion of the document at the second magnification level (812). Forexample, in FIG. 5L, in response to the detection of gesture 548 (FIG.5K), document portion 546 is displayed at a magnification leveldifferent from the level at which document 542 is displayed in FIG. 5K.The magnification level at which document portion 546 is displayed inFIG. 5L is selected so that text portion 552 is displayed at a targettext display size.

It should be understood that the target text display size is apredefined target text display size (e.g., either a default target textdisplay size or a previously stored user-adjusted target text displaysize, as described in greater detail above with reference to method 700and FIGS. 7A-7B).

While displaying the portion of the document at the second magnificationlevel, the device detects a second input indicating a second insertionpoint in the document (814), where the second insertion point isproximate to a second portion of text in the document, the secondportion of text having a second font size different from the first fontsize. For example, in FIG. 5M, gesture 554 is detected. Gesture 554indicates insertion point 555, which is in proximity to text portion 556in document portion 544. Text in document portion 544, including textportion 556, have a different font size from text portion 552 (FIG. 5L).The second input may include, in addition to gesture 554, gestures toscroll from document portion 546, where text portion 552 is located, todocument portion 544.

In some embodiments, the first font size is larger than the second fontsize (816).

In some embodiments, the first font size is larger than the second fontsize (818).

In response to detecting the second input (822), the device selects athird magnification level different from the second magnification level(824), where the third magnification level is selected so as to displaythe second portion of text at the target text display size; and displaysa portion of the document at the third magnification level (826). Forexample, in response to detection of gesture 554 (FIG. 5M), documentportion 544 is displayed at a different magnification level (FIG. 5N),such that text portion 556 is displayed at the same text display size astext portion 552 is displayed (the target text display size) in FIG. 5L.

In some embodiments, if the difference between first font size andsecond font size is below a predefined threshold (e.g., <3 ptdifference), in response to detecting the second input, the devicemaintains display of the document at the second magnification level(e.g., so as to prevent frequent small changes to the magnificationlevel of the document that could appear as unnecessary jitter to auser).

In some embodiments, the second input is a find command or a replacecommand (820). In other words, as the device switches from oneoccurrence of a term to a next occurrence of the term in the document,the device changes the magnification level at which the document isdisplayed in accordance with a font size of the next occurrence of theterm in the document.

In some embodiments, the electronic device includes a touch-sensitivesurface, and the first input and the second input are detected on thetouch-sensitive surface. In some embodiments, the touch-sensitivesurface is separate from the display. In some embodiments, thetouch-sensitive surface and the display are combined as a touchscreendisplay. For example, gestures 550 and 554 are detected on touch screen112.

It should be understood that the particular order in which theoperations in FIGS. 8A-8B have been described is merely exemplary and isnot intended to indicate that the described order is the only order inwhich the operations could be performed. One of ordinary skill in theart would recognize various ways to reorder the operations describedherein. Additionally, it should be noted that details of other processesdescribed herein with respect to methods 600, 700, 900, 1000, and 1100(e.g., FIGS. 6A-6E, 7A-7B 9A-9B, 10, and 11A-11B, respectively) are alsoapplicable in an analogous manner to method 800 described above withrespect to FIGS. 8A-8B. For example, the electronic document, insertionpoint and various magnification levels described above with reference tomethod 800 may have one or more of the characteristics of the electronicdocument, insertion point and various magnification levels describedherein with reference to methods 600, 700, 900, 1000, and 1100. Forbrevity, these details are not repeated here.

FIGS. 9A-9B are flow diagrams illustrating a method 900 of navigatingand editing an electronic document in accordance with some embodiments.The method 900 is performed at an electronic device (e.g., device 300,FIG. 3, or portable multifunction device 100, FIG. 1) with a displayand, typically, a touch-sensitive surface. In some embodiments, thedisplay is a touch screen display and the touch-sensitive surface is onthe display. In some embodiments, the display is separate from thetouch-sensitive surface. Some operations in method 900 may be combinedand/or the order of some operations may be changed.

As described below, the method 900 provides an intuitive way toautomatically zooming out at the completion of a text selection gestureto see the entire portion of text that has been selected. The methodreduces the cognitive burden on a user when navigating and editing anelectronic document, thereby creating a more efficient human-machineinterface. For battery-operated electronic devices, enabling a user tozoom in on content in a document faster and more efficiently conservespower and increases the time between battery charges.

The device displays a portion of an electronic document on the display(902). For example, in FIG. 50, a portion of document 558 is displayed.

In some embodiments, the electronic document has a predefined pagelayout and the predefined page layout is maintained while adjustingdisplay of the document (904). For example, document 558 has apredefined layout.

The device detects a content selection input (906). For example, gesture566 dragging selection handle 564-B is detected (FIG. 5O).

In response to detecting the content selection input (908), the deviceidentifies a selected portion of the document in accordance with thecontent selection input (910), and in accordance with a determinationthat the selected portion of the document includes content that isoutside of a currently displayed portion of the document, the deviceadjusts display of the document so that the entire selected portion ofthe document is displayed on the display (912). For example, in responseto the detection of gesture 566 changing selection range 560 (FIGS.5O-5Q), the portion of document 558 that is selected by selection range560 is identified. If it is determined that the selected portion (e.g.,text 562, FIG. 5Q) includes content outside a currently displayedportion of document 558, document 558 is displayed at a differentmagnification level so that the entirety of selected text 562 isdisplayed, as shown in FIG. 5R.

It should be understood that, as used herein, “outside” means theportion of selected content that extends beyond the currently displayedportion (e.g., at least some of the selected content is not currentlydisplayed). In some embodiments, adjusting the display of the documentis performed automatically without user intervention in response todetecting the content selection input or detecting an end of the contentselection input.

In some embodiments, the electronic device includes a touch-sensitivesurface, and the content selection input includes detecting a contact onthe touch-sensitive surface, detecting movement of the contact on thetouch-sensitive surface, and ceasing to detect the contact on thetouch-sensitive surface (924). For example, display 112 of device 100 isa touch screen. Gesture 566 detected on touch screen 112 includes acontact, movement of the contact, and ceasing of the contact (FIG.5O-5Q).

In some embodiments, in response to detecting movement of the contact onthe touch-sensitive surface, the device scrolls the document inaccordance with the movement of the contact (926). In other words, whenthe display is a touchscreen display and the content selection inputincludes movement of a contact on the touchscreen display, when thecontact moves proximate to an edge of the display, the document isscrolled so as to enable the user to select text outside of the portionof the document that was initially displayed when the contact wasinitially detected on the touchscreen display.

In some embodiments, adjusting display of the document is performed inresponse to ceasing to detect the contact on the touch-sensitive surface(928). For example, the entire selection range 560 is shown (FIG. 5R)when the contact of gesture 566 ceases to be detected.

In some embodiments, the content includes text and/or images (914).

In some embodiments, adjusting display of the document includes changinga magnification level for displaying the document (916). For example,from FIGS. 5Q-5R, the magnification level of document 558 was changed,going from a non-page-fit magnification level to a fit whole pagemagnification level.

In some embodiments, adjusting display of the document includesscrolling the document (918). It should be understood that the documentcould be scrolled horizontally, vertically, or both horizontally andvertically.

In some embodiments, the document has a page width, the selected portionof the document includes at least a full line of the document that spansthe page width, and adjusting display of the document includesdisplaying the document at a page width magnification level (920). Inother words, the document is displayed at a magnification level wherethe width of the document on the display is approximately equal to thewidth of the display.

In some embodiments, prior to detecting the content selection input, thedevice displays the document at a first magnification level (930), andin response to detecting the content selection input, displays thedocument at a second magnification level different from the firstmagnification level (932).

In some embodiments, prior to detecting the content selection input, thedevice enters a document-editing mode (934), and while in thedocument-editing mode, displays a soft keyboard on the display (936).For example, in FIG. 5O, document 558 is displayed in document editingmode, and keyboard 521 is displayed.

In some embodiments, prior to detecting the content selection input, thedevice enters a document-editing mode (938), and remains in thedocument-editing mode after adjusting display of the document (940).

In some embodiments, prior to detecting the content selection input, thedevice receives a document-editing input (942), in response to thedocument-editing input, displays a soft keyboard on the display (944),and in response to detecting the content selection input (e.g., afterzooming out to a page width magnification level), ceases to display thesoft keyboard (946). For example, in FIG. 5O, keyboard 521 is displayedprior to detection of gesture 566, and in FIG. 5R keyboard 521 ceases tobe displayed in response to gesture 566.

In some embodiments, in response to detecting the content selectioninput, the device displays a selection indicator indicating the selectedportion of the document and a menu including options for manipulatingthe selected portion of the document (922). For example, selection range560 and selection options menu 569 (FIG. 5R) is displayed in response togesture 566.

In some embodiments, prior to detecting the content selection input, thedevice displays a preliminary selection indicator with a first pluralityof selection adjustment affordances; and after adjusting display of thedocument, the device displays an updated selection indicator with eitherone or more of the first plurality of selection adjustment affordancesin different locations in the document (e.g., advanced by one or morewords) or a second plurality of different selection adjustmentaffordances. In particular, when the preliminary selection indicatorindicates a selection within a paragraph, the first plurality ofselection adjustment affordances enable the preliminary selection to beexpanded and/or contracted by a first unit of content; and (e.g.,character by character, word by word, or line by line). However, whenthe updated selection indicator indicates a selection including at leastone paragraph break character (e.g., a selection that extends betweentwo adjacent paragraphs) the second plurality of selection adjustmentaffordances enable the selected portion of the document to be expandedand/or contracted by a second unit of content larger than the first unitof content (e.g., paragraph by paragraph, or section by section).

It should be understood that the particular order in which theoperations in FIGS. 9A-9B have been described is merely exemplary and isnot intended to indicate that the described order is the only order inwhich the operations could be performed. One of ordinary skill in theart would recognize various ways to reorder the operations describedherein. Additionally, it should be noted that details of other processesdescribed herein with respect to methods 600, 700, 800, 1000, and 1100(e.g., FIGS. 6A-6E, 7A-7B, 8A-8B, 10, and 11A-11B, respectively) arealso applicable in an analogous manner to method 900 described abovewith respect to FIGS. 9A-9B. For example, the electronic document,insertion point and various magnification levels described above withreference to method 900 may have one or more of the characteristics ofthe electronic document, insertion point and various magnificationlevels described herein with reference to methods 600, 700, 800, 1000,and 1100. For brevity, these details are not repeated here.

FIG. 10 is a flow diagram illustrating a method 1000 of navigating andediting an electronic document in accordance with some embodiments. Themethod 1000 is performed at an electronic device (e.g., device 300, FIG.3, or portable multifunction device 100, FIG. 1) with a display and,typically, a touch-sensitive surface. In some embodiments, the displayis a touch screen display and the touch-sensitive surface is on thedisplay. In some embodiments, the display is separate from thetouch-sensitive surface. Some operations in method 1000 may be combinedand/or the order of some operations may be changed.

As described below, the method 1000 provides an intuitive way toautomatically zoom to display an object at a size that accommodates theobject or, when the object contains editable text, automatically zoom todisplay the editable text within the object at a size that accommodatesthe text. The method reduces the cognitive burden on a user whennavigating and editing an electronic document, thereby creating a moreefficient human-machine interface. For battery-operated electronicdevices, enabling a user to zoom in on content in a document faster andmore efficiently conserves power and increases the time between batterycharges.

The device displays at least a portion of an electronic document at afirst magnification level on the display (1002). For example, in FIG.5T, document 570 is displayed at a certain magnification level.

The device detects an input indicating a point within an object in thedocument (1004). In some embodiments, the point is an insertion point(e.g., a point where the device will insert additional content such astext or other objects) in response to a user request to insert content.In some embodiments, the point is proximate to the object but within ahit region for the document that extends beyond the perimeter of theobject. For example, in FIG. 5T, the location of gesture 582 indicates apoint in object 572 in document 570, and the location of gesture 580indicates a point in object 576.

In response to detecting the input (1006), in accordance with adetermination that the object includes respective editable text (1008),the device selects a second magnification level different from the firstmagnification level (1010), where the second magnification level isselected so as to display the respective text at a target text displaysize, and displays the document at the second magnification level(1012). For example, in response to gesture 582 (FIG. 5T), object 572 isdisplayed at a magnification level such that text 574 in object 572 isdisplayed at a target text display size (FIG. 5V).

It should be understood that the target text display size may be eithera predefined target text display size or a user-adjusted target textdisplay size, as described above in greater detail with reference tomethod 700 and FIGS. 7A-7B.

In some embodiments, the second magnification level is selected withoutreference to (e.g., independently of) a size of the object (1014).

In response to detecting the input (1006), in accordance with adetermination that the object does not include editable text (1016), thedevice selects a third magnification level different from the secondmagnification level (1018), where the third magnification level isselected so as to display the object at a target object display size,and displays the document at the third magnification level (1020). Forexample, in response to gesture 580 (FIG. 5T), object 576 is displayedat a best fit magnification level (FIG. 5U).

In some embodiments, the object display size is a display size where theobject is displayed at a predefined size with reference to a displayedarea of the document on the display (1022). In some embodiments, theobject display size is a display size where the object is displayed sothat it is as large as possible, while still being fully displayed inthe display area (e.g., the object is displayed at a “best fit” size).In other embodiments, the object display size is a display size wherethe object is displayed so that the width of the object is substantiallyequal to the width of the display area (optionally, with a predefinedbuffer between a perimeter of the object and the edge of the display).In other embodiments, the object display size is a display size wherethe object is displayed so that the height of the object issubstantially equal to the height of the display area (optionally, witha predefined buffer between a perimeter of the object and the edge ofthe display).

It should be understood that the particular order in which theoperations in FIG. 10 have been described is merely exemplary and is notintended to indicate that the described order is the only order in whichthe operations could be performed. One of ordinary skill in the artwould recognize various ways to reorder the operations described herein.Additionally, it should be noted that details of other processesdescribed herein with respect to methods 600, 700, 800, 900, and 1100(e.g., FIGS. 6A-6E, 7A-7B, 8A-8B, 9A-9B, and 11A-11B, respectively) arealso applicable in an analogous manner to method 1000 described abovewith respect to FIG. 10. For example, the electronic document, insertionpoint and various magnification levels described above with reference tomethod 1000 may have one or more of the characteristics of theelectronic document, insertion point and various magnification levelsdescribed herein with reference to methods 600, 700, 800, 900, and 1100.For brevity, these details are not repeated here.

FIGS. 11A-11B are flow diagrams illustrating a method 1100 of navigatingand editing an electronic document in accordance with some embodiments.The method 1100 is performed at an electronic device (e.g., device 300,FIG. 3, or portable multifunction device 100, FIG. 1) with a displayand, typically, a touch-sensitive surface. In some embodiments, thedisplay is a touch screen display and the touch-sensitive surface is onthe display. In some embodiments, the display is separate from thetouch-sensitive surface. Some operations in method 1100 may be combinedand/or the order of some operations may be changed.

As described below, the method 1100 provides an intuitive way toautomatically switching back and forth from a user-specifiedmagnification level in a document-display mode to a predefineddocument-editing magnification level in an editing mode. The methodreduces the cognitive burden on a user when navigating and editing anelectronic document, thereby creating a more efficient human-machineinterface. For battery-operated electronic devices, enabling a user tozoom in on content in a document faster and more efficiently conservespower and increases the time between battery charges.

The device displays at least a portion of an electronic document at auser-specified magnification level (1102). In some embodiments, theuser-specified magnification level is a magnification level selected bythe user from a plurality of possible magnification levels. For example,the device receives requests to adjust (e.g., increase or decrease) themagnification level of the document (e.g., pinch or depinch gestures ona touchscreen display) prior to receiving a request to enter adocument-editing mode. For example, in FIG. 5X, document 584 isdisplayed at a user-specified magnification level in response to gesture590 (FIG. 5W).

While the document is in a document-display mode, the device receives arequest to enter a document-editing mode distinct from thedocument-display mode (1104). For example, gesture 592 (FIG. 5X) is arequest to enter a document editing mode.

In response to receiving the request to enter the document-editing mode(1106), the device enters the document-editing mode (1108), and displaysthe document at a predefined document-editing magnification leveldifferent from the user-specified magnification level (1110). Forexample, in FIG. 5Y, in response to gesture 592, document 584 isdisplayed in document editing mode and at a particular magnificationlevel for editing of a cell (e.g., cell 594) in worksheet 591.

In some embodiments, both entering the document-editing mode anddisplaying the document at the predefined document-editing magnificationlevel are performed in response to receiving the request automatically,without further user input. Enabling a user to both enter thedocument-editing mode and zoom the document to a magnification levelthat is comfortable for editing by performing a single gesture reducesthe number of steps that are performed by the user to begin editing thedocument, thereby increasing efficiency and ease of use of the device.In some embodiments, after displaying the document at thepredefined-document editing magnification level, the device receivesrequests to adjust (e.g., increase or decrease) the magnification levelof the document (e.g., pinch or depinch gestures on a touchscreendisplay) prior to receiving a request to exit the document-editing mode.In these circumstances the device would zoom from the currentuser-adjusted document-editing magnification level to the prioruser-specified magnification level upon exiting the document-editingmode.

While the document is in a document-editing mode, the device receives arequest to exit the document-editing mode (1112). For example, in FIG.5Z, gesture 598 on button 597 is a request to exit document editingmode.

In response to receiving the request to exit the document-editing mode(1114), the device exits the document-editing mode (1116) and displaysthe document at the user-specified magnification level (1118). Forexample, in FIG. 5AA, in response to gesture 598, document 584 isdisplayed at the same user-specified magnification level as in FIG. 5X.

In some embodiments, both the exiting the document-editing mode anddisplaying the document at the user-specified magnification level areperformed in response to receiving the request automatically, withoutfurther user input. Enabling a user to both exit the document-editingmode and zoom the document to a magnification level at which thedocument was previously displayed by performing a single gesture reducesthe number of steps that are performed by the user to return to adocument-display mode from the document-editing mode, thereby increasingefficiency and ease of use of the device.

In some embodiments, in response to receiving the request to enter thedocument-editing mode, the device determines whether thedocument-editing magnification level is within a predefined threshold(e.g., 5%, 10%, 20%, 30% or some other reasonable threshold that reducesjitter) of the user-specified magnification level. For example, if thedocument-editing magnification level is 100%, the user-specifiedmagnification level will be within the predefined threshold if it is amagnification level between 80% and 120%. In accordance with adetermination that the document-editing magnification level is notwithin the predefined threshold, the device enters the document-editingmode and displays the document at a predefined document-editingmagnification level different from the user-specified magnificationlevel. In contrast, in accordance with a determination that thedocument-editing magnification level is within the predefined threshold,the device enters the document-editing mode while maintaining display ofthe document at the user-specified magnification level. In other words,when the document-editing magnification level is within the predefinedthreshold, the device does not zoom to a document-editing magnificationlevel that is different from the user-specified magnification level.

In some embodiments, the electronic device includes a touch-sensitivesurface, and the request to enter the document-editing mode is detectedon the touch-sensitive surface (1120). In some embodiments, thetouch-sensitive surface is separate from the display. In someembodiments, the touch-sensitive surface and the display are combined asa touchscreen display. For example, gesture 592 is detected on touchscreen 112.

In some embodiments, the request to enter the document-editing mode is adouble tap gesture detected on the touch-sensitive surface (1122). Forexample, gesture 592 (FIG. 5X) is a double tap gesture.

In some embodiments, the request to enter the document-editing modeincludes an indication of an insertion point in the document and theinsertion point is proximate to a respective portion of the document(1124). In response to receiving the request to enter thedocument-editing mode, the device scrolls the document to place therespective portion of the document in a central region of a documentdisplay area. (e.g., a central region of the display or a central regionof a portion of the display that doesn't include a soft keyboard)(1126). For example, the location of gesture 592 (FIG. 5X) indicates aninsertion point in cell 594. In FIG. 5Y, cell 594 is approximatelycentered in the part of touch screen 112 where document 584 isdisplayed.

In some embodiments, the request to enter the document-editing modeincludes an indication of an insertion point in the document and theinsertion point is proximate to a respective portion of the document(1128). Entering the document-editing mode includes providing an inputinterface for editing the respective portion of the document proximateto the insertion point (e.g., a text cursor and keyboard or a form fieldfor entering a value) (1130). For example, in FIG. 5Y, while in documentediting mode, keypad 595 and edit field 596 are displayed.

In some embodiments, in response to receiving the request to enter thedocument-editing mode, the device inserts a text cursor at the insertionpoint (1132). In response to receiving the request to exit thedocument-editing mode, the device removes the text cursor (1134). Forexample, a text cursor may be inserted into cell 594 when enteringdocument-editing mode, and the text cursor is removed from cell 594 whenexiting document-editing mode.

It should be understood that the particular order in which theoperations in FIGS. 11A-11B have been described is merely exemplary andis not intended to indicate that the described order is the only orderin which the operations could be performed. One of ordinary skill in theart would recognize various ways to reorder the operations describedherein. Additionally, it should be noted that details of other processesdescribed herein with respect to methods 600, 700, 800, 900, and 1000(e.g., FIGS. 6A-6E, 7A-7B, 5A-SB, 9A-9B, and 10, respectively) are alsoapplicable in an analogous manner to method 1100 described above withrespect to FIGS. 11A-11B. For example, the electronic document,insertion point and various magnification levels described above withreference to method 1100 may have one or more of the characteristics ofthe electronic document, insertion point and various magnificationlevels described herein with reference to methods 600, 700, 800, 900,and 1000. For brevity, these details are not repeated here.
